PSI 9000 DT Series
By linking together a number of differently configured sequence points, complex progressions can be created.
Smart configuration of the arbitrary generator can be used to match triangular, sine, rectangular or trapezoidal wave
functions and thus, e. g. a curve of rectangular waves with differing amplitudes or duty cycles could be produced.

Example 7
Focussing 2 cycles of 1 sequence point:
A sequence configured as in example 3 is run.
As the settings demand that the end offset (DC)
is higher than the start, the second run will revert
to the same start level as the first, regardless
of the amplitude achieved at the end of the first
run. This can produce a discontinuity in the total
progression (marked in red) which may only be
compensated with a careful choice of settings.

Example 8
Focussing 1 cycle of 2 sequence points:
Two sequence points run consecutively. The
first point generates a sine wave with increasing
amplitude, the second with a decreasing one.
Together they produce a progression as shown
to the left. In order to ensure that the maximum
amplitude in the middle occurs only once, the
first sequence must end with a positive half
wave and the second start with a negative half
wave, as shown in the diagram.

Example 9
Focussing 1 cycle of 4 sequence points:
Point 1: 1/4th of a sine wave (start angle = 270°)
Point 2: 3 sine waves (ratio of frequency to
sequence point time = 1:3)
Point 3: Horizontal ramp (f = 0)
Point 4: Falling ramp (f = 0)
